This study applies a structural equation model to explore the relationships among service quality, satisfaction, switching barrier and loyalty for ocean freight forwarders. The shippers that have higher volumes of import or export trade are selected for empirical analysis. A questionnaire survey was adopted to collect the shippers’ perceived data related to their freight forwarders about service quality, satisfaction, switching barrier, and loyalty. The research findings indicate that service quality has a positive and significant impact on loyalty; however, this impact is intensified via the mediators of satisfaction and switching barrier. Moreover, satisfaction has a positive and significant impact on switching barrier and loyalty. Switching barrier also positively and significantly influences customer loyalty. This research suggested that ocean freight forwarders should promote the service quality to effectively retain their customers.
